UNITED STATES cnoaen LAWSON 1121mm; or new PLEASANT, Noam cAnoLnuL HEATER FOR CARBUBETOBS.

Application filed October 18, 1919. Serial No. 531,545.

To all whom it may concern:

Be it known that I, Gsonon Lawson Han- RlN, a citizen of the United States, residing at Mount Pleasant, in the county of Cabarrus and State of North Carolina, have Invented new and useful Improvements in.

object the provision of a heating drum as-- sociated with and surrounding a part of the carburetor and receiving heat, from the ex-' haust of the engine, the purpose of the device being to heat the gasoline within the carburetor so that the gasoline may be more readily converted into vapor and whereby a very eflicient and more easily exploded. mixture will be produced.

An important'ohject is the provision of a device of this character which is in the na ture of a drum encircling the bowl of a carburetor and provided with clamping means whereby it may be secured upon the carburetor.

Another object is the provision of a device of this character which is provided with a tube extending from the drum into the carburetor whereby to introduce exhaust gas within the carburetor.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufaiture, easy to install, eflicient and fuel saving in,nse, durable in service, and a general improvement in the art.

\Vith the above and other objects and advantages in view, the invention consists in the details of construction to he hereinafter more fully described and claimed andillustrated in the accompanying drawings in which I Figure 1 is a side elevation of a motor and carburetor showing my device in position,

Figure 2 is a plan view of a carburetor showing: the device in position,

Figure 3 is a cross sectional view showing the carburetor in elevation.

Figure 4 is :1 plan view of my device dctachcd,

Figure 5 is a side elevation thereof.

Referring more particularly to the drawings. the letter A designates an internal combustion engine of the type used upon a wry popular make of automobile, B designates'the exhaust manifold. and C desgnates the carburetor;

In carryingpntrmyinvention I'provide a c rculardlf'iimlqwhloh is formed as a ring 'likeaneiirbr which is hollow and the inner prrpheryofthiidrum is of such size as to snugly-receive or en age upon the bowl of thecarburetorc with the top surface of the drum flush with'the top of the bowl. The drum is secured in posit-ion by means of a plurality of cli s 11 which are secured upon the upper e ge of the drum by suitable screws 12 and.which projectjover and engage upon the top of the bowl;

At one side the drum is providedwith a boss-13 which is threaded "andfadapted to be connected by a coupling 15 ,to a pip; 16 which leads into the exhaust mani- 1 In order to introduce exhaust gas within .pass through the tube 16 into the drum and efi'ect heating of t e carburetor. It will also be apparent that when the valve 18 is open the exhaust gases within the drum 10 will pass into the carburetor'and be mixed with the vaporized gasoline therein whereby to forma more efficient and more highly explosive mixture than if only cold air were admitted.

From the foregoing description and a study of the drawings it will be ap arent that I have thus provided a ery simp e and inexpensive heating drum attachment for carburetors which will effectually heat the gasoline vaporized and which will consequently economize on fuel as it is well known that a hot mixture explodes more readily and gives more power than a cold mixture. It will also be apparent that the device may be readily attached and that it will eilirienlly perform all the functions for which it is intended. L

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the sco e of the subjoined claims.

Having thus described my invention, I claiu 1. In combination with the exhaust manifold and carburetor of an internal combustion engine, means for heating the carburetor comprising a hollow ring-like drum disposed in encircling relation to the carburetor, a plurality of clips pivotally mounted upon the top of said drum and engageableover the upper edge of the carburetor bowl, a. 7

pipe connected with one side of the drum and connected with the exhaust manifold. and a valved tube for effecting communion lion between said drum and the czu'buret'on 2. In combination with the exhaust manifold and carburetor of an internal combustion engine, means for heating the ('nrburotor comprising an integral hollow ring shaped drum disposed in encircling relation to the carburetor bowL a plurality of clips pivoted upon said drum and engaging over the top of the carburetor bowl, and a. pipe connected with said drum and connected with the exhaust manifold.

In testimon whereof I affix m signature.
